on the other side as the earth is literally pulled away from the ocean from the moon. we get the strongest tides and if you're in the right place at the right time the moon even provides enough energy to. incoming water. turtle nature of the power. and the idea of using the tides for humans purposes has been around for ages several hundred years ago enterprising engineers constructed flour mills powered by the daily. people have looked to harness the type for electricity generation in the twentieth century a number of projects around the globe were proposed but were decried as economic madness for a time it looked as if the proponents of title power were fighting a losing battle but in one nine hundred sixty three the rance river estuary in brittany france was blocked off to start construction on what would be the first

industrial sized power station in the world in the process of one and a half million cubic meters of water were displaced for seventy five construction site. twenty four turbines have a capacity of two hundred forty megawatts to this very day but the hefty price tag dampen enthusiasm for such plants in the country but that didn't deter others who knew could be done better and more cheaply. today. around the world. it's possible to construct a good plan. i

think it's safe to say. that was the driving force behind. the concept even before. thirty eight when he was. he had already the idea of a power station. where to build one instance while working. he travelled. home which is remarkable. despite the fact that it's up in the arctic circle already. thriving port in the

one nine hundred sixty s. . for innovative engineering projects like baby. because of the many. fluctuations in the water level as the tide rushes are more pronounced than otherwise would be the views can be breathtaking for the last ice age having stripped away the top layer sediment leaving mostly exposed. water. purposes the most ideal spot for the world title power plant was here. because it's. connected directly to the via an especially outlet compared with a concurrent competing project in france. much less invasive site prep was required. there was absolutely nothing nothing at all people thought were going about it. there was no way you can build a tidal power plant like you can and. perhaps the most important

breakthrough was a revolutionary method of construction. powerhouse. greatly reduced environmental damage like that scene in france. the climate proved to be another potential obstacle. we had to find a concrete composition that would survive such severe winters. and we managed to make concrete.

that we had invented we developed. that is the core of the entire facility. so once the construction was complete they simply attaching joint pontoon filled the dock with water and tugs the whole complex to the chosen site along the way they took the opportunity to monitor how the structure fared in rough seas in total the trip from more months to measured just a hair under one hundred kilometers. an hour triumph. he had done this before everything went well he took us one day to transport the planes. mounted to the underwater foundation this was a great success and once we had done it we get universal recognition. in the decade since those accomplishments have withstood the test of time and have been adopted the world over the floating method has become an industry staple project engineers

everywhere cut costs by as much as up to fifty percent and the station itself has also held up well against father time the original power house operated its entire useful life without problems or substantive repair and when engineers tested the state of the two thousand they found that the walls of the structure were in great shape even after nearly forty years of constant freezing and thawing of the arctic frigid waters. at the center of this russian engineering feat a french hard turbine with a rotatable propellers was the most complex and most expensive part of the power plant it could generate electricity as the tide came in with water rushing into the blocked off as well as in reverse thanks to the special made blade system however most of agree that it's often better to just use in one direction because as the water rushes back out to sea it operates at ninety percent efficiency but only fifty percent in the other direction. we bought. us.

from france it was a. good but also very complex and expensive one of the units was equipped with a french german and the other one was left empty forty five years ago we had hoped that we would eventually make a turban. and so we did it is an orthogonal turban. based on what's called a turbine and uses blade shape similar to airplane we. can vary in depends on the speed of the water goes of which way the water flows in the turbine spins in the same direction with no significant change in efficiency and after being tested out for a few years and eventually found its way into a brand new title power plant that was being added onto the existing structure. to produce a new turbine and powerhouse whose hydro turned to mush one of russia's leadership

and submarine makers and a testament to the relative simplicity of the new voter system the whole complex complete with turbine generators was constructed in around six months as a factory just outside of the white city about hunger and in two thousand and six following as much fanfare that would normally accompany the launch of a new ocean liner the floating power plant made its maiden as well as final voyage to. and just like the original it was towed on pontoons into the bay instead of tearing down the existing structure they left it in place and simply attached. to the face of it which by the way had been made a monument to russian science and technology. outfitted with new digital equipment the original control room still remains the hub of human activity here surprisingly simple an actual operation. power plant can be.

but whatever the arrangement. were also developed tested. in japan. they were able to achieve an efficiency thirty percent. he said they gave up working on such projects and went there with both and we picked it up rees mean we changed the blade said words as well as the section to. end today we are too busy fissions the factor is as high as any two percent are going to go with that is we increase it would were some thirty eight percent to eighty two brewers and. you want as a result from our design is more energy efficient than the french turban which was considered the classical type of the instance of this worthless use in.

it took years if not decades to get that turbine just right but now with that in hand bruce hydros institute of energy structures is ready for the next challenge to the next logical stage was to achieve capacity. measures in where is will need to. downsize you have a totally different scale course and require a different approach. that water is about the emitter is deep there's always been the plan with three year olds to a bind the generators capacities for megawatts the roller is five meters in diameter and the bleed off long bruce hydro plans to test out the new design in the

connected. there are sensors installed here including pressure sensors angular rate sensors and turbine air speed sensors. their readings enable us to evaluate a turbine's performance. we have an analysis center that collects all these data and studies them to find patterns and correlations. here's where the incoming data get analyzed. even the temperature of various parts of the construction. they can monitor how the turbine performs under various conditions different speeds or alternating flow one thing they've noticed is that because the turbine spins in the same direction of the flow it's ideal for use in the water column in which the direction of. of course there are other kinds of wave energy

converters out there but these engineers are confident that they're designed for something other simply. some power plants that are shaped like a snake but that's naik often gets carried away by the current. the installation is too heavy complex and difficult to secure with all the joints that serve to generate electricity. there are also hydraulic turbines that. their design is way too intricate and leaves something to be desired. there are floating power stations but they also get carried away if there's. by and large humanity. first we came up with a concept of an orthogonal turbine and then we successfully applied it in designing a way for our plan. and the groundwork for including such wave columns in future

projects has already gotten started this past year alone hydro built a prototype up and. it will produce electricity for the local grid as well as give the engineers back at the institute precious data to improve the next generation of ocean energy snatchers. could help. with an inevitable. ok proceeding. even if. it was.

to counteract the. sense that tide only comes in and out twice a day all of its potential energy has to be harnessed in short bursts to help smooth out this and other peaks there is another type of hydro plant out there this one requires an artificial lake but relies on the natural power of gravity. pumped storage plants. energy right. hundred meters of. electricity generated. take advantage of lower prices and pump the water back into the upper reservoir more often than not. demand in the morning and. they can

also be used in tandem with plants balanced approach to energy. pumped storage power. turbines each with a capacity of two hundred megawatts of generation and two hundred twenty megawatts and pumping about it was designed to regulate the energy balance in moscow region and neighboring areas in central russia the power plant was built back in the one nine hundred eighty s. in the one nine hundred ninety s. it did reach design to capacity in two thousand but is currently operates at full power. practice pumped storage power stations are normally placed in a mountainous areas with greater water pressure european part of russia doesn't have the kind of terrain however still managed to set up a fairly efficient facility in spite of an average incline of around one hundred. stations efficiency is seventy four percent of you couldn't hear it as a station is russian made including its pump turbines manufactured by power

machines and its engine generator is produced by the general electric heavy engineering plant that's also part of the individual capacity of each turbine two hundred megawatts is quite powerful few pumped storage power plants in the world can boast that. as you just heard the work of the whole plant is made by a company called power machines located in st petersburg they specialize in big powerful equipment like this giant ship propeller. storage are being constructed at the company's metal factory which has been in operation for over one hundred fifty years over the decades around twenty seven hundred turbines with a total combined capacity of over three hundred gigawatts. the factories making four by directional turbines each of which can crank out two hundred ten megawatts those new turbines are needed because at present in moscow region there's

a pressing need for new capacity. as a result lose hydro is pushing ahead with the second phase here that. it's ok to seven hundred fifty meters south of the existing facility design work started in two thousand. and the first cement was poured in mid two thousand and eight as one of the biggest construction projects in russia at the moment something like sixty million cubic meters of earth to be moved it's approaching suez canal like for fortune's the new expansion comes with a price tag of just over two billion dollars. this gives us a perfect overview of the current state of the construction site really. we can see how far along. in terms of completion. the water ducts measure seven and a half meters in diameter are made out of twenty individual sections three bars welded together before they're hold over to the main construction site where concrete is eventually for in the end two hundred thirty six cubic metres of water

will be able to burst through the pipes every second similar foreign facilities have chosen to use. made of metal is prone to sun. when we were designing our. we considered employing such metal and even an underground conduit but in the end. economic and safety factors we decided to may not be the best in comparison to. one hundred percent. according to roos hydras plants the first two turbines will be in place by the end of two thousand and twelve while the third is slated for next year and the fourth in two thousand and fourteen and that really can't come soon enough with analysts saying that moscow region alone could use an additional one and a half of spare capacity in fact in order to get the added waters are quickly as possible the structure is a mess and generators are made part is taking place around the clock with five thousand people employed in three shifts for new generators will boost existing

capacity by eight hundred forty megawatts one will reach that powerhouse by travelling eight hundred pipes the new. cubic meter pool is being built right next to the existing. one end of the. lower reservoir rather than build an entirely new one the fourth largest pump storage plant in the world it's obvious that if russia should make use of its immense potential for tidal power generation and put it into practice storage power plants would definitely come in handy particularly to compensate for tidal plants natural cyclical. no together or separately these technologies are unlikely to say. needs for electricity but they could soon play a growing role in completing the overall energy picture especially by adding stability to sometimes unreliable sources like solar and wind but most important of all the some of the greenest methods of power generation out there interestingly enough

perhaps the only ones that don't depend on the sun in one way or the other only time will tell if there ever become more than just a need for cation. for this edition of technology we'll see you next time and until then enjoy the ride. his wedding falls fifteen go. to cal. kilograms of rice one seldom flatbreads. and. one is the bride in a bad mood. to tell the group he. is a.
